Description

Technical Field

[0001] The utility model relates to the technical field of air film pavilions, in particular to an air film adjustable lighting window. Background Art

[0002] The air-inflated gym is a large balloon-shaped shed that can support an indoor sports venue. It uses air pressure to support the membrane surface. No beams or columns are needed for indoor support, and a large-span structure can be easily achieved. Compared with traditional sports venues, it has the advantages of low construction cost, high space utilization, simple maintenance and use, and repeated relocation. As a new type of fitness facility, the air-inflated gym enriches the supply of public venues to a certain extent, and provides a solution to meet the multi-level and diversified fitness needs in the era of national fitness.

[0003] At present, the gymnasium air membrane adopts a double-layer membrane structure, and most of them use shading membrane materials to avoid the problem of high indoor temperature in summer. It can better meet the effect of indoor light projection, but the lights need to be turned on during the day, which increases the energy consumption of lighting. If the project has a high demand for lighting, part of the shading membrane material is usually replaced with a light-transmitting membrane material during the membrane processing process to form a lighting belt, which can save the energy consumption of turning on the lights during the day, but sunlight will increase the indoor temperature and increase the energy consumption of air conditioning and refrigeration;

[0004] The above two solutions each have their own advantages and disadvantages, and they cannot be taken into account at the same time. In addition, whether the air membrane has lighting is determined in the design stage. Once used, it cannot be replaced later, and cannot provide users with a changeable and flexible use environment. Therefore, an air membrane adjustable lighting window is needed. Utility Model Content

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] Example: Reference Figure 1-3 The air film adjustable lighting window shown in the figure comprises a lighting outer film 1 and a light-shielding inner film 2, wherein the lighting outer film 1 is arranged to cover the outer side of the light-shielding inner film 2, and an interlayer cavity is formed between the lighting outer film 1 and the light-shielding inner film 2, and a plurality of evenly distributed lighting inner films 21 are arranged on the light-shielding inner film 2 at intervals;

[0025] An adjustable shading film 3 is installed in the interlayer cavity between the outer side of the shading inner film 2 and the daylighting outer film 1, and the adjustable shading film 3 slides to cover the outer side of the daylighting inner film 21;

[0026] A driving mechanism for driving the adjustable light-shielding film 3 to move is installed on the light-shielding inner film 2 .

[0027] Based on the above structure, when in use, the adjustable shading film 3 can be driven to move by the driving mechanism, so that the adjustable shading film 3 covers the lighting inner film 21 or is separated from the lighting inner film 21, so as to achieve the effect of allowing sunlight to be projected into the interior of the air-inflated pavilion or blocking the sunlight. The lighting effect of the air-inflated pavilion can be flexibly changed according to actual use needs, and the use effect is better.

[0028] Among them, the coverage area of ​​the adjustable shading film 3 is larger than the light-transmitting area of ​​the lighting inner film 21, thereby ensuring that the adjustable shading film 3 plays a good shading role when covering the outside of the lighting inner film 21, avoiding the appearance of light-transmitting gaps, and ensuring its shading effectiveness.

[0029] Furthermore, the driving mechanism includes a pull rope, a first pulley 4 and a capstan 6, one end of the pull rope is fixed to the upper end of the adjustable shading film 3, a mounting keel 8 is fixed to the outer top wall of the shading inner film 2, one end of the first pulley 4 is fixed to one side of the mounting keel 8 through a support frame, the other end of the pull rope passes through the first pulley 4 and then extends downward and is wound on the capstan 6, and the capstan 6 is rotatably mounted on the lower inner part of the shading inner film 2;

[0030] A threading hole 22 for the pull rope to pass through is opened at the lower part of the shading inner film 2. A second pulley 9 is rotatably connected to the outer side of the shading inner film 2 near the upper end of the threading hole 22. The pull rope is passed through the second pulley 9. After passing through the second pulley 9, the pull rope changes direction and extends vertically downward.

[0031] When it is necessary to drive the adjustable shading film 3 to move, it is only necessary to rotate the capstan 6 so that the pull rope is wound around the capstan 6 or the pull rope is lengthened, and the adjustable shading film 3 can be separated from the lighting inner film 21, or re-covered on the outside of the lighting inner film 21, thereby realizing the controllable adjustment of the position of the adjustable shading film 3, achieving the effect of flexibly adjusting the lighting of the air-inflated pavilion, and facilitating the user to change the lighting effect of the air-inflated pavilion according to actual use needs. The operation is simple and the use is convenient.

[0032] Furthermore, a counterweight 5 is hung at the lower end of the adjustable shading film 3 through a rope. When the rope is stretched, the counterweight 5 pulls the adjustable shading film 3 to slide downward along the outer side of the shading inner film 2 and makes the adjustable shading film 3 cover the outer side of the daylighting inner film 21.

[0033] Through the setting of the counterweight 5, when the pull rope is stretched, the counterweight 5 pulls the adjustable shading film 3 to slide downward along the outer side of the shading inner film 2, and finally makes the adjustable shading film 3 cover the outer side of the lighting inner film 21. At this time, the stretching is just fully stretched, so that the adjustable shading film 3 can be smoothly reset and cover the lighting inner film 21, so as to achieve the effect of blocking the outside sunlight from projecting into the interior of the air-supported pavilion.

[0034] Furthermore, a positioning member for limiting the position of the capstan 6 is provided on the capstan 6, and a driving member for driving the capstan 6 to rotate is also installed on one side of the capstan 6, wherein the positioning member can be a positioning bolt, and the driving member can be an operating handle 7 or a servo motor, or the operating handle 7 and the servo motor can be used simultaneously. The operating handle 7 can be used to facilitate the staff to manually rotate the capstan 6 to retract and release the pull rope, and cooperate with the positioning bolt to limit the rotated capstan 6, so that the capstan 6 will not rotate uncontrollably. The servo motor can realize automatic retraction and release of the pull rope, which is more convenient to use. At the same time, when using the servo motor, the use of the positioning member can be eliminated, and the locking function of the servo motor itself can be used to limit the position of the capstan 6, which can also achieve the purpose of limiting the position of the capstan 6.

[0035] Working principle of the utility model: during daily use, when it is necessary to adjust the lighting effect in the air-film pavilion, it is only necessary to turn the operating handle 7 (or start the servo motor) to drive the winch drum 6 to rotate, so that the pull rope is wound on the winch drum 6 or the pull rope is lengthened, and the adjustable shading film 3 can be separated from the lighting inner film 21, or re-covered on the outside of the lighting inner film 21, thereby realizing controllable adjustment of the position of the adjustable shading film 3. When the shading film 3 is adjusted to separate from the lighting inner film 21, the external sunlight is projected into the air-film pavilion through the lighting outer film 1 and the lighting inner film 21, thereby realizing a good lighting effect. When the adjustable shading film 3 covers the outside of the lighting inner film 21, the adjustable shading film 3 cooperates with the shading inner film 2 to prevent sunlight from entering the air-film pavilion and achieve a shading effect. Therefore, the lighting effect of the air-film pavilion can be flexibly changed according to actual use needs, and the use effect is better.

[0036] Finally, it should be noted that the above is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present utility model shall be included in the protection scope of the present utility model.
